RL 33 and 300 RUM

[Catfur]

So, since that was pretty much the only powder on earth slower than 7828 I could find in any quantity, I have a jug-o-RL33.

Does anybody have any ideas for loading 200G Accubonds and 230 Berger Hybrids in a 300 Ultramag?

I'm burning 95 grains rl33 in my 300 rum with the 225 hornady in rem brass lit by a 215@ 3.650" oal.
1" 200 yard groups out of a 9# stock factory lh bdl without a brake.
Don't know about the 200 a-bonds but if you walk her up a few grains from the 225 I'm sure you'll be fine.
